Description

technical field [0001] The invention relates to numerical control processing equipment, and further refers to a numerical control milling machine and a gear grinding machine for processing spiral bevel gears. Background technique [0002] In the prior art, the structure and adjustment links of mechanical spiral bevel gear processing machine tools are the most complicated among gear machine tools. With the advancement of technology, the spiral bevel gear processing machine tool adopts the structure shown in Figure 1, which uses a computer to directly control three linear axes (ie X, Y, Z axes) and three rotational axes (ie A, B, C axes) , that is, the machining motion of the mechanical spiral bevel gear processing machine can be simulated, so as to process the spiral bevel gear. The CNC spiral bevel gear processing machine tool converts the complex mechanical structure into software control, realizing the informatization and intelligence of spiral bevel gear processing.

Problems solved by technology

However, the above-mentioned equipment is a kind of intentionally simulating the structure of a mechanical machine tool. The rotation mechanism of the cradle is changed to the linkage of X and Y axes to realize the rotation of the tool around the axis of the cradle, and the function of the tool tilt mechanism is changed to the swing of the B axis. The role of numerical control technology has not been fully utilized, so there are still the following main defects:

[0003] 1. There is a sector gear or friction wheel with a large diameter on the Z-axis sliding table 11 in the Z direction of the linear axis, and the processing technology is not good;

[0004] 2. The shape of the workpiece box 41 is complicated, the manufacturability of processing is not good, and it is difficult to guarantee the processing accuracy;

[0005] 3. All the weight of the workpiece box 41 is pressed on the sector gear or the friction wheel, so it is difficult to unload;

[0006] 4. The X-axis sliding table 21 in the X direction of the linear axis is a gantry, and the Y-axis sliding table 31 in the Y direction of the linear axis moves vertically on the gantry. The servo motor and the hydraulic balance cylinder are erected very high, and the protection is very difficult;

[0007] 5. For the sake of environmental protection and saving, the development direction of spiral bevel gear milling is dry cutting, that is, no coolant is added during processing, the cutting speed is very fast, and the heat is taken away by chips, which requires that hot chips cannot fall on the bed. , so as not to affect the thermal deformation of the machine tool, the device in Fig. 1 is difficult to do this;

[0008] 6. The machine tool has many parts and occupies a large area, so it is inconvenient to load and unload the workpiece
